unsigned char -> unsigned int conversion

[Henry Spencer]

Morris Keesan asks, in discussion of the C Reference Manual:

   > ..........elsewhere it implies the existence of "unsigned long" in
   > some implementations.
   
   ............. but where "elsewhere" does it "imply" unsigned
   long?

Section 4 of the K&R CRM notes:

	...
	(On the PDP-11, unsigned long quantities are not supported.)
	...

Also, the problem he reports (V7 cc bounces "short int" because it's just
translating "short" to "int" everywhere) is present in the vanilla V7 cc
as well as the BBN one.
